(a) Droplet diameters achieved as a function of applied liquid flow rate Q for different conductivities K. (b) In the dimensionless parametrization of the flow rate and droplet (Maißer et al., 2013), the droplet diameters from the different conductivities fall on the same curve. (c) A side-view microscopy image (0.92 µm pixel size) of the 2PP-3D printed CCT. The 40 µm ID of the electrospray tip exactly matches the ID of the utilized fused silica capillary and the 30° angle at the tip is seamlessly transferred to the angle of the formed liquid cone. The tip–liquid interface is indicated with the dotted red line. |
